Development stages: 1 clinical project, ridinilazole, a Phase III clinical candidate for the treatment of C. difficile infections, and 2 discovery/pre-clinical projects
Novelty: 1 novel project, ridinilazole, a Phase III clinical candidate for the treatment of C. difficile infections that belongs to a new chemical class of antibacterials and has a new drug target, mode of action and no known cross-resistance to other antibacterial classes
Regulatory approvals: 0 approvals for priority pathogens
Access plans: Its 1 late-stage R&D project has a project-specific access plan that is a licensing agreement to expand availability to access countries, though this plan does not address affordability.
Stewardship plans: Its 1 late-stage R&D medicine project lacks a project-specific stewardship plan.

Opportunities for Summit

Improve access plans and develop stewardship plans for ridinilazole. Summit has committed to ensure access and stewardship plans are in place for its antibacterial candidate in late-stage development, ridinilazole, through its agreement with the Wellcome Trust. So far, Summit has entered into a regional licensing agreement for ridinilazole with Eurofarma Laboratorios for 21 countries in Latin America, including 13 access countries. Summit can improve its access plans for access countries by committing to an equitable pricing strategy and/or looking for licensees across other regions of the world. Summit has not developed worldwide stewardship plans for ridinilazole yet. As examples of stewardship plans, the company can commit to decouple sales incentives from sales volumes and/or become involved in antibacterial surveillance activities.

Changes since 2018

  • Initiated Phase III clinical trials for ridinilazole in February 2019, with data expected in 2021. 
  • Expanded its R&D pipeline in April 2019 to include the discovery-stage DDS-04 series project targeting Enterobacteriaceae, identified via its proprietary Discuva Platform.
  • Entered into a new exclusive license and commercialisation agreement in December 2017 with Eurofarma Laboratórios SA in Latin America for ridinilazole. Eurofarma is responsible for regulatory approvals in the territory (Brazil and 20 other Latin American countries) and Summit retains commercial rights worldwide.

Evaluated: medicine & vaccine pipelines for priority* bacteria & fungi

A.1 R&D investments 
Summit invested USD 56 million in the development of antibacterial medicines in 2017 and 2018. As with all other SMEs evaluated, Summit was not scored in this indicator. 

A.2.1  Pipeline size of three projects
Summit reports three projects targeting priority pathogens in its pipeline. The company focuses on antibacterial medicine development, with its three projects equally divided between discovery, pre-clinical and clinical (Phase III) stages of development.

A.2.2 One clinical-stage novel project
Summit’s clinical-stage medicine pipeline for priority pathogens consists of one new R&D project. Summit has one late-stage antibacterial medicine project that is considered novel: ridinilazole, for C. difficile infections, which meets all criteria set by WHO for innovativeness, including belonging to a new chemical class and having a new target, mode of action and no cross-resistance to other antibacterial classes. 

A.2.3 Vaccines in the pipeline
Summit is not eligible for this indicator as it is not active in vaccine development. 

A.2.4 Three candidates targeting critical and/or urgent priorities
Summit’s pipeline includes one clinical medicine candidate in Phase III (ridinilazole) that targets C. difficile; one pre-clinical medicine candidate (SMT-571) that targets N. gonorrhoeae; and a discovery platform (DDS-04) that targets Enterobacteriaceae, including ESBL-producing Enterobacteriaceae and CRE. These pathogens are among those that are considered critical and/or urgent R&D priorities for limiting AMR, as identified by WHO and/or the US Centers for Disease Control and Prevention (CDC).
A.3 Intellectual capital sharing

As an SME, Summit was not scored for this indicator, in line with the external stakeholder consensus defined by the Foundation.

A.4 Access plan for 1 project; no stewardship plans
Summit has one late-stage R&D project targeting priority pathogens. Summit plans to commercialise ridinilazole with its own sales force in the USA. Other territories could be covered independently or through commercialisation agreements with third parties. For example, Summit has entered into a regional licensing agreement for ridinilazole with Eurofarma Laboratorios, one of the largest pharmaceutical companies in Brazil and present in more than 20 countries in Latin America, including 13 access countries.* Summit does not report specific clauses regarding affordability or accessibility in the agreement, or any stewardship plan. 

Pipeline targeting priority pathogens: 3

B. Responsible Manufacturing

As a small- to medium-sized enterprise (SME), Summit is not evaluated in this Research Area. Its most advanced antibacterial candidate is ridinilazole, and the Benchmark notes that Summit reports planning its manufacturing programmes to cover the needs of Phase III clinical trials as well as the commercial launch of ridinilazole. Within these plans, two third-party suppliers will be engaged to manufacturer the product. Summit states that it recognises the importance of reducing the impact of manufacturing discharge on antibacterial resistance and expects to develop its environmental risk-management strategy with respect to antibacterial discharge over the coming years. Summit was not scored on these activities.

C. Appropriate Access & Stewardship

As a small- to medium-sized enterprise (SME), Summit is not evaluated in this Research Area. It has no antibacterial and/or antifungal products on the market.

* Bacteria and fungi that have been identified as priority R&D targets for limiting AMR, by either the WHO and/or the Centers for Disease Control and Prevention (CDC).
